A neigboor has told me, if a individual takes care of a
Person on medicare. They get paid by medicare.
Even if a wife takes care of her medicare covered husband.

Do you think this is true??

I do not believe so - Medicare Coverage: What does Medicare Cover? And Benefits at MedicineNet.com (http://www.medicinenet.com/script/main/art.asp?articlekey=42212)

I am not aware of this coverage either.

No, there is "home health care" payments by medicare, the group doing the service has to be a licensed group who is registed and approved to provide medicare services by their state.
